<p>A power trigger is provided having time qualified and sequential event capability. Digital data representing an input signal is converted (42) into a power signal. The power signal is compared (44) to a trigger level. A trigger signal is generated when the power signal violates the trigger level for either at least or less than a specified time duration (48). Alternatively, the trigger signal may be generated on the occurrence of a sequence of such violations.
